Different deceleration thresholds s

Different deceleration thresholds should be set for different roads. When braking on a road with a high adhesion coefficient, the wheel angle deceleration of the peak adhesion coefficient reached is small, so the high adhesion coefficient should have a large deceleration when all other conditions are the same Threshold value, and low adhesion coefficient pavement should have a smaller threshold value, anti-lock control should form a cycle, the anti-lock control state should be run to the unstable region of the tire characteristic curve, so the threshold value The angular deceleration value greater than when the peak adhesion coefficient is reached is:    At the same time, if the deceleration threshold value is relatively small during actual braking. In practice, due to uneven road surface, sensor error and other noises, different deceleration thresholds should be set for different deceleration roads. When braking on a road with a high adhesion coefficient, the peak adhesion coefficient of the vehicle's angular velocity reached Small, so the adhesion coefficient should have a larger deceleration threshold when the other conditions are the same. The low adhesion coefficient pavement should have a smaller threshold, and anti-lock control should form a cycle, so the anti-lock control state should be run to the unstable region of the tire characteristic curve. Close to the actual control is difficult to achieve, ECU is prone to malfunction.
